IMPROVEMENT-IN. COFFEE-POTS.

TO ALL WI-IOM IT MAY CONOERN Beit known that I, JOHN ZIMMERMAN, of Royalton Centre, in the countyot` Niagara,.:1nd State of New York, have invented a new and improved Codec-Pot; andI do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and in which the drawing represents a vertical section of'my invention.

In my improved coii`ee-pot the coiee is subjected, ii-rst to the action of the steam,ras it rises from the water in the pot to the condehser, and afterwards to the action of the condensed water, owing bach to the potA from the condenser. A

In orderl that others skilled in 'the art'to which my invention appcrtains may be enabled to"make and use the same, I will proceed to describe it in detail.

In the drawings, A A represent the boiler or body of. the coi'ee-pot, in which the water is boiled, provided with a handle, B, and a spout, C. In the top of this pot I place a vertical chamber, D, perforated at d d d, and over the whole extent of its bottom withV small holes. This chamber, being made slightl'yconical, vis suspended at the point d near its centre, where it bears against the odge of the aperturein the top of the boiler A. Its Whole length is abouty two-thirds the length of the boiler. Inside of the chamber D, I place a loose strainer, E,

4iu shape the frustum of a cone, its dimensions at the top being suchas to permit it to drop into the chamber D only tothe point show-'n inthe drawings, in which position aspace will be left 'between itsA bottomy and the v bottom of the chamber D, and anarrow but slightly increasing space will -be left between its walls and the is capable of being fastened down securely.

walls of the chamber D, from its top towards its bottom. The chamber D, it will be observed, isless conical than'the strainer E. F is a cover, which closes the top 'ofthe chamber D, and in the centre ofwhich, ltted to it by a. steam-tightjoint, is avertical tube, G, terminating at its lower end in a conical chamber, H, with forani-- inated bottom, and at its upper end in an inverted conical condensing-chamber, I, provided with a lid, z', which The operation of my improved codec-pot is as follows: `The boiler is partially or quite filledv with water, and the chamber D is then inserted in its place. The cod'ee is placed in the strainer E, which is adjusted in the l position shown in the drawing, and the cover F is fixed to the chamber D. The coffee-pot isfthen -subjected to the action of heat, and as the water boils the rising steam passes through the bottom and sides of. the strainer E, and in every direction through the coffee within it, enters the conical chamber H, and passes through the pipe G to the 'chamber I, lwhere it is condensed and'tricklcs bach through tube Gr and chamber H, dripping upon the coifee in the strainer, which it percolates, and dually escapes'intoth'e boiler whence'it started.

My' coffee-pot has been thoroughly tested, and'found to extract the essence of the coffee more rapidly and perfectly than any other previously used. I It is; besides, cheap, simple, and can he understood and operated by domestics ofthe dullest comprehension. Besides, it is perfectly safe from explosion. Whenever the steam fails to condense with suicientrapidty, if such should ever be the case, it will simply elevate the chamber D -or the cover F slightly, and pass freely out around them. No valves are attached, to rust and get out'of order, but thechamber D and the cover F themselves operate as plug-valves, and rise, under pressure oftho'steam, with the same readiness and safetyas the cover ofthe old-fashioned singlc-ichamber coffee-pot. Having thusA described my invention, what I claim asnew,'and desire to secure by Letters Patent, is- The coffee-pot above described, consisting ot' the boiler A, chamber D, strainer E, cover F, and tube G,

bearing the chambers Hand I, all arranged and'combined substantially as and foi the purpose specified.

To the above speciiicationpf my improvement, I-have signed my hand, this twenty-seventh day of June, 1867.
